Important: Do not route a transducer cable down the trolling motor
power cord. Route the transducer cable down the side of the mount,
then into the bow console. Provide enough excess sonar cable to
allow the motor to make three (3) complete 360 turns.
Electronics, depth finders in particular, should be connected directly to the
main engine or an accessory battery. Do no connect your electronics to
the trolling motor battery.
Establishing a Common Ground
MotorGuide recommends isolating the trolling motor battery/batteries from the
main engine battery.
Electrolysis Issues – Using the engine starting battery as a source of power
for any trolling motor may cause electrolysis on metallic parts.
9 If you have followed the battery wiring and installation instructions in
this manual and your boat continues to have electrolysis issues, you
will need to separate the trolling motor from any other boat electronics.
9 Remove the engine starting battery from the wiring configuration of the
boat and isolate the power circuit for your trolling motor.
Establish a Common Ground: Common ground means the ground for
the main engine accessories and your trolling motor are connected to the
same negative ground terminal.
Not having a common ground can cause severe corrosion or electrolysis.
If left unchecked, damage may be caused to your trolling motor and boat.
Establishing a common ground connection will allow increased sensitivity
and improve detail on a sonar display.
Recommendations
Battery Type – The recommended battery is a 12-volt Deep Cycle battery.
Circuit Protection – MotorGuide recommends installing a 50 amp
manual-reset circuit breaker in line with the trolling motor positive leads
within (1.8 m) 72 inches of the battery(s). To order a circuit breaker kit,
contact your local Service Dealer, request kit number MM5870 or a 50
amp circuit breaker and a power switch.
Wire Size – For optimum performance, MotorGuide recommends the use
